21. Insert a 0.7mm feeler in between the caliper mount and the rotor at several spots on both sides of the rotor, on both the left and right sides of the motorcycle. If there is binding, loosen the axle holder nuts and adjust the fork leg in or out as required, then snug the axle holder nuts again and re-check.

any suggestions?

Have a look at the caliper when you squeeze the brakes on. Is it moving? Then let go - is it moving again? The caliper movement should be almost indiscernable, if any. I've had a brake go spongy when one caliper slider pin seized up, causing it to bend it on application, and spring back on release.

However, chances are it's air in the lines. Try bleeding it again. You might try wrapping a bungee to hold the brakes on hard - pump them up, then hold them on with the bungee, and leave it sitting like that overnight. A lot of times that will allow air to migrate up to the master cylinder and fixes the problem.
